3 potential downsides to soybean oil
Soybean oil is regarded as a heart-healthy oil because it contains a large amount of omega-3 and omega-6 fatty acids. However, it contains other harmful compounds, such as saturated fats and triglycerides acid, which can cause inflammation. As a result, a high intake of refined soyabean oil may negatively affect human health.
1. Increases risk of diabetes
Type II diabetes is caused by persistently elevated blood glucose levels, which are accompanied by insulin resistance or decreased insulin production. Approximately 90 percent of patients with type II diabetes are overweight or obese.
An animal study on mice revealed that those fed with soybean oil developed risk factors for diabetes more than the mice fed coconut oil. These risk factors include:
2. Liver diseases
The liver detoxifies your blood, controls cholesterol levels, helps with digestion, processes nutrients, etc. Obesity increases the risk of nonalcoholic fatty liver disease (NAFLD). Soybean oil appears to be linked to NAFLD.
NAFLD is one of the primary causes of liver dysfunction in the United States, affecting 30 to 40 percent of Americans.
Fat builds up in the liver and causes symptoms, including:
3. Heart diseases
Obesity is known to increase the risk of cardiovascular diseases. Along with the accumulation of fat, soybean oil may increase the risk of heart diseases due to the following:
- Lipid peroxidation: Oxidized lipids produced by frying polyunsaturated fatty acids (PUFAs), such as soybean oil, which cause atherosclerosis (arteries harden due to fat deposition in the walls of arteries).
- High consumption of omega-6 fatty acids: A high omega-6 fat intake raises inflammation, which is a major risk factor for cardiovascular diseases.
- Lowers high-density lipoprotein (HDL) cholesterol: A high soybean oil diet reduces HDL cholesterol (good cholesterol), which may imply impaired cholesterol transfer.
Partially hydrogenated soybean oil contains trans-fats, which are associated with metabolic issues and cardiac diseases.
4. Immune toxicity
Studies have shown that soybean oil is hazardous to both types of immune cells that fight against infections and increases the risk of infections in individuals who consume soybean oil.
